My daughter was born after 14 hours of labor with no issues, in a baby friendly hospital, and with what all of the medical professionals assured me was a perfect latch. The nurses kept telling me she would fall asleep soon, that all newborns do, but she was up for 7 hours after birth, most of the hours latched onto me. Everyone assured me that she was cluster feeding, that I was doing a great thing by breastfeeding her, and we were sent home with no concerns being expressed, despite her 10 percent weight loss that I was told was normal. We had a weight check in later on that day with the lactation consultant. We found out she lost 17 % of her body weight.
